CU-T insertion, also known as intrauterine device (IUD) insertion, is a contraceptive method involving the placement of a small T-shaped device into the uterus. The “CU” stands for copper, as some IUDs are made of copper which creates an environment that is toxic to sperm, preventing fertilization. This highly effective and long-lasting form of birth control is reversible, with the ability to prevent pregnancy for several years. The insertion is typically performed by a healthcare provider, involves minimal discomfort, and can be done in an outpatient setting. It’s important to discuss the benefits, potential side effects, and suitability of CU-T insertion with a healthcare professional before deciding on this contraceptive method.
